Housing for a small animal

Abstract

A housing for a small pet animal has a housing body, a plurality of unit plates and attaching mechanism for the unit plates. The unit plates form a shape which fits in the housing body in a horizontal state when combined with each other on an plane. The attaching mechanism is formed on at least one of the unit plates and the housing body to detachably attach the unit plates to the housing body. The unit plates form a partitioning plate for dividing an inner space of the housing body into an upper space and a lower space when the unit plates are combined on a plane in the housing body and are attached to the housing body by the attaching mechanism. The unit plates form stages when at least one of the unit plates are attached to the housing body at a level different from the other unit plates.

What is claimed is: 
     
       1. A housing for a small pet animal, the housing comprising: a housing body;   a plate-shaped member composed of a plurality of unit plates having complemental fitting edges, said plurality of unit plates forming a shape which generally coincides with a horizontal cross-section of said housing body when combined with each other on a plane so as to fit said corresponding complemental fitting edges; and   an attaching means formed on at least one of said unit plates and said housing body to detachably attach said unit plates to said housing body,   wherein said plate-shaped member forms a single partitioning plate for dividing an inner space of said housing body into an upper space and a lower space when said unit plates are combined with each other on a plane in said housing body so as to fit said corresponding complemental fitting edges and are attached to said housing body by said attaching means, and   wherein said plate-shaped member forms a plurality of stage plates when said plate-shaped member is in a disassembled state and at least one of said unit plates is attached to said housing body at a level different from the other unit plates.   
     
     
       2. The housing apparatus as recited in claim 1, wherein one of said unit plates includes an opening which allows the small pet animal to pass through and a cap detachably fitted in said opening. 
     
     
       3. The housing apparatus as recited in claim 1, wherein said housing body includes a plurality of wires extending horizontally and spaced at predetermined distances, wherein said attaching means includes a hook portion detachably engaged with one of said wires and provided on an edge portion of said unit plate, whereby said unit plates are detachably attached to said housing body with said hook portion engaged with said at least one wire.   
     
     
       4. The housing apparatus as recited in claim 1, wherein said unit plates are provided with an upwardly protruded edge portion formed along an outer edge portion of said unit plates.
